Hamlyn no Violin-Hiki (Violinist of Hamelin)

Medusa, the beast from classic Greek mythology with the power to turn any warrior to stone, has been terrorizing a nearby village for years. Every year, the village must offer up a sacrifice to prevent Medusa from coming in and turning the whole place into a stone garden. The village's leaders have become seriously fed up and have hired Hamelin and his gang of music-themed warriors to go in and stop Medusa. Whether or not Hamelin's troupe is competent enough to do so is another matter entirely.
